Comment 3 for bug 1486137

I mean, this is definitely reproducible, it's also clear that cinder-backup.log sometimes isn't created. It only happens on hpcloud servers at the gate. We'd need someone with an account there to spin up a similar flavor and see if they can figure out why cinder-volume and cinder-backup aren't creating logs.

Since Clark mentioned that HP Cloud servers have a different flavor, I wonder if we're running out of disk space before cinder-volume can create it's log file. (I can't imagine getting a flavor with so little disk space though.)
